High-Speed Steel Jobber Drill Set
The Drill America KFD29J-SET contains 29 high-speed steel jobber length drill bits with a black and gold oxide finish. Round shanks fit standard drill chucks for general-purpose drilling tasks. The 135-degree split point design helps reduce walking and starts holes cleanly. All pieces store in a durable metal case for organisation.
Suited For General Metal Drilling
This set serves mechanics, fabricators and maintenance teams drilling steel, iron and other ferrous metals. The jobber length provides standard reach for bench and handheld work. Builders needing carbide tips for hardened steel, masonry bits for concrete or specialised cobalt alloys for stainless steel should select different tooling.
29 Piece Incremental Sizing Range
The set covers sizes from 1/16 inch through 1/2 inch in 64th-inch increments. This density of sizes lets operators match hole diameter closely to tap, bolt or rivet requirements. Projects requiring larger diameters, smaller micro-drills or non-fractional metric steps will need supplementary bits.

Questions about this item
How do I install these bits in my drill chuck, and what step do people often miss?
Open the chuck fully, insert the round shank straight, then tighten securely; the step often missed is not centering the shank before final tightening.
What maintenance will these high-speed steel bits need over time?
Sharpen the 135-degree split point when cutting slows, wipe off chips after each use, and apply light oil to prevent rust on the black and gold oxide finish.
What limit appears first when drilling many holes in a row?
Heat buildup at the 135-degree split point dulls the edge fastest during sustained drilling, so pause to let bits cool between holes.
